J.- G. BAKER LOG CABIN CONSTRUCTION Filed Feb. 25, 1942 4 Sheets-Sheet 4' Inventor Patented 'June 8, 1943 UNi'i I 1 Claim.

The present invention relates to new and useful improvements in log cabins, and has for its primary object to provide, in a manner as hereinafter set forth, ajoint ofnovel construction for the logs which will be positively weatherproof.

Another very important object of the invention is to provide a log cabin of the character described comprising a novel construction, combination and arrangement of door and window frames, corners, et cetera, whereby the structure will be self-supporting and the use of an inner frame or studding rendered unnecessary.

Other objects of the invention are to provide a log cabin construction of the aforementioned character which will be comparatively simple, strong, durable, attractive in appearance and which may be manufactured and erected at low cost.

All of the foregoing and still further objects and advantages of the invention will become ap- 1 parent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in front elevation of a door opening in a log cabin constructed in accordance with the present invention.

modification may also be used in the door construction.

Referring now to the drawing in retail, it will be seen that reference numeral I designates a concrete foundation. Plates 2 are mounted on the foundation I. The plates 2 support joists 3. The joists 3 support a floor 4 and a sub-floor 5.

Erected on the plates 2 are horizontal wall logs 6, the lowermost of certain of which the ends of the joists 3 abut, as shown to advantage in Figure 2 of the drawings. The legs 6 are formed to provide top and bottom bearing surfaces 1 and 8, the inner faces 9 of said logs being fiat. The outer surfaces of the logs 6' are substantially rounded, as at It]. Rising from the tops 7 of the logs 6 are longitudinal tongues II, said tongues being on the inner portions of said logs. The tongues II are engageable in grooves I2 which are provided therefor in the superjacent logs. The tops and bottoms of the 1025 6 are further provided with opposed, complemental substantially V-shaped grooves I3 defining a passage for the reception of a suitable sealing medium. The bottoms 8 of the logs 8 are still further provided, on their outer portions, with depending lips or aprons M which are engageable in rabbets I5 which are provided therefor in the tops of the subjacent logs. The rabbets I5 are inclined outwardly slightly to better shed water.

The ends of the wall logs 6 which abut have formed therein opposed saw cuts or kerfs I6. The kerfs I6 extend diagonally between the tops and bottoms of the logs 6 from the inner sides of the tongues II to the inner portions of the lips or aprons I4. The kerfs I6 are for the reception of metallic splines I! which render the joint substantially air and water-tight even though the logs should shrink.

In Figures 1, 2 and 3 of the drawings, a door frame is designated generally by reference nu- The frame I8 includes vertical side members I9 of substantially the cross-sectional shape shown in Figure 3 of the drawings. Extending between the lower end portions of the side members 19 is a threshold 26. A header 2| extends between the upper end portions of the side members I9. The joint between the threshold 20 and the subjacent log 6 is substantially the same as the joints between said logs. This is also true of the plates 2 and the logs 6 resting thereon. Facing strips 22 are provided on the inner faces of the members I9 and 2| of the door frame l8.

Mounted above the header 2| is a cap log or member 23. The outer portion of the header 2| has formed therein a rabbet 24. The rabbet 24 accommodates an apron 25 which depends from the outer portion of the cap log 23, thus providing a water-tight'joint without the necessity of using flashing. The header 2|, it will be observed, is spaced below the cap log 23 and the apron 25 for permitting the walls to settle. This is indicated at 26 in Figure 2 of the drawings.

In Figures 7, 8 and 9 of the drawings, a window frame is designated generally by reference numeral 21, said frame having mounted therein a casement sash 28. The window frame 2'1 includes an outwardly protruding sill 29. Mounted on the inner portion of the sill 29 and projecting inwardly therefrom is a stool 30. De-

pending from the inner edge of the sill 29, be-

In Figure 10 of the drawings, an inside corner structure is designated generally by reference numeral 34. In this inside corner, one of the logs 35 has formed in one end portion a comparatively long stepped rabbet 36. The adjacent end of th other log 31 abuts the longitudinal Wall of the rabbet 36 and has formed therein a complemental but comparatively short rabbet 38. The rabbets 36 and 38 accommodate a vertical corner post 39. In Figure 11 of the drawings, an outside corner is indicated at 40. In this construction the right angularly extending logs alternately cross and project beyond each other. The inner sides of the comparatively long logs, as at 4 I, have formed therein vertical grooves or channels 42 for the reception of tongues or tenons 43 which project from the opposed, abutting ends of the comparatively short logs, as at 44. The end portions of the tongues I l are removed to permit the crossed logs to rest fiat on the subjacent logs. side corner piece is indicated at 45.

An in- Referring now to Figures 12 and 13 of the drawings, what may be referred to as a wall rafter log is indicated at 46. A log rafter resting on the member 46 is indicated at 41. At the points where they intersect, the members 46 and 41 are notched or recessed and interlocked, as at 48. The upper portions of the rafter logs 41 are preferably flattened to facilitate mounting and securing thereon the roof boards 49.

In the modification of the door frame structure illustrated in Figure 14 of the drawings, the outer sides of the vertical side members 50 and the adjacent sides of the tongues or tenons 5| of the wall logs 6 have formed therein saw cuts or kerfs for the reception of metallic strips 52 of angular cross-section. This modification may also be used in the construction of the window frames.

In the modification of the outside corner construction shown in Figure 15 of the drawings, the inner sides of the comparatively long logs and the abutting ends of the short logs have formed therein opposed, diagonally-extending saw cuts or kerfs for the reception of metallic splines 53. Thus, in this embodiment the grooves 42 and the tongues 43 shown in Figure 11 of the drawings are omitted.

It is believed that th many advantages of a log cabin constructed in accordance with the present invention will be readily understood, and although a preferred embodiment is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to'which will fall within the scope of the invention as claimed.

I claim:

A log cabin construction comprising a foundation, plates mounted on said foundation, superimposed wall logs mounted on said plates, and a door frame mounted in the wall logs, said frame including a threshold, vertical side members rising from said threshold, a header extending between the upper portions of the side members, a cap log mounted above the header, and an apron depending from the outer portion of said cap log, the header having a rabbet therein accommodating the apron, said cap log and the apron being spaced from the header. 7
